XD</p><p>I am:</p><ol><li>Deeply nostalgic about the 16-bit era of computing and its graphic limitations</li><li>Deeply concerned that I use as little of my instance admin's (admittedly ample) data storage as possible</li></ol><p>So, I almost never post videos, and when I post pictures, I either post as very compressed <a href="https://polymaths.social/tags/webp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>WebP</span></a> (not my favorite image format, but it's the best format for low-fidelity/high-compression images that <a href="https://polymaths.social/tags/gotosocial" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>GoToSocial</span></a> supports), or "lossy"-compressed PNGs.</p><p>I have a utility on my phone (<a href="https://f-droid.org/packages/ru.tech.imageresizershrinker/" rel="nofollow noopener noreferrer" target="_blank">Image Toolbox</a>) that can reduce PNG files by reducing the number of colors, but it's not great at picking the colors.</p><p>When I have the time and presence of mind to do so, I will take the PNG into GIMP and either use its conversion function to reduce the number of colors (to something like 32 or maybe 64, possibly as low as 4 or 8), or (like in the above case) I'll actually hand-select the important colors in the image and tell GIMP to reduce the image to just those colors.</p><p>In this case, the original screenshot PNG was 83KiB, which I managed to bring down to 16KiB through the manual color reduction process (down to just 6 colors).</p><p>If you peruse the <a href="https://polymaths.social/tags/lossypng" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>LossyPNG</span></a> hashtag, there are plenty of examples. Some are obviously reduced (and are reminiscent of graphics on 16 bit machines like the <a href="https://polymaths.social/tags/amiga" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Amiga</span></a> or <a href="https://polymaths.social/tags/atarist" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>AtariST</span></a>), but some look quite good for how severely reduced they were.</p>
